Connects to eBay, Shopify, Best Buy, and Etsy to search product listings, view details, pricing, availability, and seller information. Muse can help you find items, compare prices across platforms, and browse shop catalogs.

Example request: "Find wool running shoes under $150 across eBay and Etsy to compare prices and sellers"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Commerce Bridge to help me. It is a free service with an MCP server at https://commercebridge-isaiahduprees-projects.vercel.app/api/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_ebay: Search live eBay listings by keyword and/or category across 8 sites (US, GB, DE, AU, CA, FR, IT, ES), built on eBay's official Browse API. Returns id, title, price, condition, seller feedback, shipping, image, categories, and URL per listing. Returns an honest `credentials_requir
- get_ebay_item: Get one eBay item's full detail — description, brand/MPN/GTIN, color, item specifics, images, return terms, availability, item end date — by REST item id or legacy numeric id. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials pr
- get_ebay_items: Bulk-fetch full item detail for up to 20 eBay items in a single call, given comma-separated item ids. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials provisioned.
- search_ebay_sold: Sold/completed-item price comps. This needs eBay's Marketplace Insights API, which is a limited-release approval separate from the base Browse API. Until that is enabled on the upstream deployment, this always returns a 501 `not_enabled` gate rather than a fabricated result — tha
- search_shopify_products: List any public Shopify store's product catalog straight from that store's own /products.json — no keys, no auth, works today. Returns title, vendor, product type, tags, price range, variants, images, and URL per product. Pass a bare storefront domain, e.g. `allbirds.com`.

- get_bestbuy_product: Get one Best Buy product by SKU, full detail. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without BESTBUY_API_KEY provisioned.
- search_etsy: Search Etsy's site-wide active listings by keyword, built on Etsy's official Open API v3 (app-only, no OAuth). Returns title, description, price, quantity, tags/materials, favorites, images, and shop per listing. Errors honestly until this engine is fully live upstream: currently
- get_etsy_listing: Get one Etsy listing by id, full detail — the only endpoint where Etsy's API populates `views` (search and shop-listings results always have `views: null`, since Etsy doesn't carry that field there). Errors honestly until this engine is fully live upstream: currently returns `not
- get_etsy_shop: Get one Etsy shop by shop_id or shop_name — name, listing counts, favorites, total sold, aggregate review count/average. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `creden
- get_etsy_shop_listings: List one Etsy shop's active listings, optionally keyword-filtered within the shop.
